I have a water injection kit from snows that goes off of map pressure. The engine in question is a supercharged ls6. the pulley on the blower is a 5 pound pulley but my VE changes through the revs so I hit 9 pounds at 3600 RPM and drop down to 3 at redline. I'm fine with the engine almost catching up to the blower since I'm trying to be conservative and I could safely get another 5k RPM out of the blower. My problem is with a kit that injects water based off of manifold pressure, would the low VE which is causing the 9 pounds of manifold pressure lead to too much water being injected at that particular time? I'm also thinking 9 pounds of boost is 9 pounds of heat as well. I'm running straight water injection for max knock resistance. Any advice would be appreciated.
